Summary of Recent Trends • Evidence of a recent decline or downward shift in abundance in northern stocks • The major Interior Fraser stocks have recently declined to among the lowest levels recorded. • South coast stocks tributary to Georgia Basin have remained at relatively low abundance, many since the early 1990’s • West coast Vancouver Island stocks have remained at relatively modest levels since early 1990s’.
The distribution of anglerdays in 1968 and 2006 1968 – 222 streams Anglerdays 2006 – 169 streams

By and large, the advent of steelhead hatchery streams in BC…. • Came about as a response to federal plans to enhance pacific salmon • Intended to mitigate against increased interspecific juvenile competition and increased adult interceptions
Update - Streams Stocked with Hatchery Steelhead There are 423 stocks in 391 watersheds. We’ve stocked as much as 18% of BC’s steelhead streams, but for a brief time.
BC Steelhead Stream Classification Policy • strong emphasis on wild stock conservation • catch and release sport fishing on wild stocks, province wide • procedures and conditions regarding the designation of “hatchery-augmented” streams • framework for assessment (abundance based)
Other Policies - Interception Update • Federal Policy • Steelhead not part of Federal Wild Salmon Policy • mandatory release from salmon gillnet and seine fisheries, but many fisheries remain unselective • Skeena seine and gillnet fisheries – F based steelhead policies • Fraser seine and gillnet fisheries – was recently an F based policy; moving toward protecting a proportion of the run in only some gillnet fisheries?? • Dean channel fisheries – mandatory weedline • International – Article IX: Steelhead • “In fulfilling their functions, the Panels and Commission shall take into account the conservation of steelhead.” • In general, mortality rates due to bycatch in salmon fisheries have been increasing since the late 1990’s.
Water Mgmt Update • Water supply issues in southern third of BC • Licencing limited to surface waters • Ground water remains unlicenced commodity (exception for mega-projects; EA’s) • Water Act does not explicitly deal with values other than was is termed “benefitial use” (i.e. direct use). • Water shortage and flows for values other than for domestic, agriculture or industrial use are being addressed in an increasing number of places through WUP processes (BC Hydro) and localized watershed planning initiatives. • Proposals for IPP’s everywhere
Update - Land Mgmt and Issues • Private Lands • RAR – new regulation applicable to new development in or about riparian areas. • Very limited in scope • No broad scale riparian restoration initiatives or incentives on private lands, only project scale. • Access issues • Forest Lands • Pine Beetle – hydrologic change; cattle access to rivers • Riparian protection (S1-S6, LRMP’s) • Community Watershed designation where ECA is limited. • Oil, gas and mining exploration (e.g. Sacred Headwaters Coal Bed Methane) • Carbon Credits
Fish Habitat Projects • LWD • Fertilization • Substrate placement • Channel construction or modification • $3.5 million/year
